Answer:

It is actually 3 centered 2 electron bond (found in Be2H4;B2H6) Or 3 centered 4 electron bond (found in Al2Cl6). Electron deficient compound minimise electron deficiency by undergoing dimerisation or polymerisation through bridge bond. But some conditions applied for bridge bond-

Central atom must have vacant orbital and back bond must be absent.

Steric repulsion from the surrounding atom must be less.
